Using exoplanets to study dark matter

More than 5,000 planets have been discovered beyond our solar system, allowing scientists to explore planetary evolution and consider the possibility of extraterrestrial life. Now, a UC Riverside study published in Physical Review D suggests that exoplanets, which are planets orbiting stars outside our solar system, could also serve as...

In search of dark matter

RIVERSIDE, Calif. — An international team of scientists that includes University of California, Riverside, physicist Hai-Bo Yu has imposed conditions on how dark matter may interact with ordinary matter — constraints that can help identify the elusive dark matter particle and detect it on Earth. Dark matter — nonluminous material...
